Popis: Cells of Streptococcus cremoris were grown in the presence of various levels of glycerol and sodium acetate. The cultures were harvested in the maximum stationary phase and the lipids subsequently extracted and analyzed. The presence of either metabolite resulted in stimulated lipid synthesis. The lipids were fractionated into five major groups by thin layer chromatography. These groups were designated as containing phospholipids, mono-, di-, and triglycerides, and esterified fatty acids or wax esters. The fatty acid compositions of these fractions in the lipid from the control (no added metabolite) and treated cells were determined. The presence of acetate favored the synthesis of phospholipids, and influenced the percentage of 18:1 acid(s) incorporated within this fraction.
